Slope Test Review

Front

What are the slopes of parallel lines?

Back

Identical.

Front

What is the slope of two parallel lines?

Back

Slope that is the same.

Front

How do you find the slope of a line passing through two points?

Back

Use the formula: \( m = \frac{y_2 - y_1}{x_2 - x_1} \) where (x1, y1) and (x2, y2) are the points.

Front

What is the slope of the line that passes through (6,7) and (4,2)?

Back

\( \frac{5}{2} \)

Front

What does the slope represent in a linear equation?

Back

The rate of change of y with respect to x.

Front

What is the slope-intercept form of a linear equation?

Back

\( y = mx + b \) where m is the slope and b is the y-intercept.

Front

What does a slope of 0 indicate about a line?

Back

The line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

The line is vertical.

Front

What are opposite reciprocals?

Back

Two numbers whose product is -1; e.g., 2 and -\( \frac{1}{2} \).

Front

If two lines are perpendicular, what is true about their slopes?

Back

Their slopes are opposite reciprocals.
